I STEAM-HEATING SYSTEM.

Application filed March 9, 1908. Serial No. 419,934.

-*To alluihom'it'my concern." Be 1t known that I, DANIEL BROADBELT, a

citizen "of the" United States, an .of New-York, borough of Broo aresident lyn, county Q'KingS, andl State of New York, have in- 'vented'certain new and useful Improvements the like.

in Steam-Heating Systems, of'Which the followingis a full, clear, andexact description.

l `.Tliisinvention relates more particularly to hea-ting Systems forhouses, apartments and The primary object of'ithe invention .is toprovidef'siinple and eiicient -means whereby proper=.jcircl1latio n 'maybe obtained in the ,heatingeomiections in' such a Way that the usualpounding of the pipes may be eectually overcome, and' to provide meansWhere- ;bysultableVV ventilation' may be secured "throughoutthe entiresystem or at parts thereof-lto'prevent' the: collection of air in.'

the .pipes4 Alfurther object'of the invention is to provide meanswhereby Vunnecessary pressure is aut()mz'iticallyv relieved',-and toprevent leak- -."agc-orf'other'injury to theconnectionsv by reason'vofany excess of pressure.

these and other objectsin view the inventlonwill be `he'reinafter moreparticu- "larlydescribed with reference to the accom- .p afnylngg'"ldrawings', which form a part of A-tlii's' specification, and-.Will thenbe pointed {cnt in 'the claires atthe-end ofthe descripf. thefdravvings,l?igure1 is a vertical Sb-tion h1-ugh a'building in which is ar-Vf-ranga eone'formcf heating System embody" lng."illy'1l,irizen'tion';and Fig. 2 is a vertical radiators 14.- Ther sectiknfshovving theboilerand the arrange- -1rfent ofone of the vent or stand-pipes- .40,

These "twofmain .steam pipes 15 and 16 may.extend :thefentire 'height'of the-building, and are ,connetedftogetherby' a horizontally-extend- .ingsteam'pipeQl, and a short pipe 22conlnect'sthis pi e 2l"to ,the-'steam space of the ghe pipes 15` and. 16extend specification of Letters raient.

indicated at 25. *Aswvill be seen when' steam theboiler throughthe pipe22 to the pipe 21 and through said pipe to the vertical steam pipes l5and lG to any or all of the radiators, and in case of condensationl 'ofthe steam, the Water will return through the pipes and 1G to the returnpipes 24 and into the boiler-again, though it will be understood that aseparate return pipe from the radiators may be employedif desired.

To prevent air from collecting in the pipes or connections and torelieve said connectionsv of any excess of 'pressure so as to avoidpounding and togive proper cirtmlation to connect- With the return'pipes2.4 on each side o'the boiler, and to each of said pipes 2G may beconnected Aa: vent or stand pipe 27 in 'each of which is a valve 28, andvsaid stand is generated in 'theboiler it Willpass from 5 the steam, Iprovide pipes `2G"\`vhic h may y pipes may be of the same diameter andex-V p tend urpivardly a suitable distance so as; to prevent theordinary pressure in theboiler fromforcing the Water out yof said pipes,the upper endso which are open'and ma v be provided With a shortL-shaped'pi'pe 29 with the open end extending.doivinvard so as toprevent dnstand the like from entering said pipe. The stand pipes 27Yarc connected above the Water line to the return pipes 24 by means of ahorizontally-extending vent pipe 30, andsaid pipe may be controlledbetween each of the stand'l and the return pipes by a valve 3l. Theremay be any desired number of stand pipes and one of said pipes may be atthe rear .of theboiler and may bev provided with a valve 32. Q The pipe30 is connected by short angular pipes'orconnections 33 to the returnpipes 24 non each Vside ofthe boiler below the point Where the steam' lpipes join the return pipes, vand from the angular, connections 33extend Yupward and downward vent pipes 34. These vent pipesl 34 are.each substantially- U-shaped inform, and are each provided with avalve35, and

said pipes project upwardfar .enough to prevent the Water from beingforcedout'of the vents 34 when the valves35 are opened,`

but will permit thel steam or air or any eX- cess pressure in theheating system to be relieved at these pointswithoutthe loss of theWater, as the angular 4connections ypro- A vide a direct connection 'fortheiret-urnof:

anyl Water to the boiler. Byimeans. of the connections shown the entiresystem or any.y

part thereof may be relieved of any ,excess u sions are preventedandcertain partsof the system automatically relieved of any excesspressure in the pipes Vand the parts eectually lrelieveduof any air thatmight: collect' therein or 'otherwise cause pounding inthe-` i pipes,and that said systemis such that it Patent maybe applied -to theordinary heating system with very little expense.

Having thus described my invention, I claim as -new and desire` tosecure byLetters 1. The combination lwith a boiler of verticallyarranged steam' pipes and heating ldevices in communicatiomthere'with,of return pipes connected to the steam pipes and also to the boilerIbelow the water line thereof, connections between the boiler and thesteam pipes above the water line for the passage of steam to said steampipes, a plurality of vent or .stand pipes extendingupward and havingtheirup'per ends open and-adapted to contain a column of water ofagreater height than. the .water line of the boiler, connections formingcommunication 'between the' standl pipes and the Vboiler below7 thewaterline thereof, pipe connections between the stand pipesand saidreturn pipes above the water. lineof the boiler, said connections alsoforming communication between the standpipes, valves in said,connections for controlling the same, together with Urshaped vent pipesarranged in the pipe connection between the stand pipes andcommunicating with the return pipes.
